摘要
PURPOSE: A call processing method for a video calling supported terminal, a call processing server and a mobile communication system for the same are provided to keep visual communication even though a sender communicates with a receiver who has a terminal not supporting visual communication and to designate an alternative image in advance and to enable a receiver to designate an alternative image in advance. CONSTITUTION: When a call is transmitted from an originating terminal to a destination terminal, an HLR(Home Location Register)(120) controls an originating MSC(110) to set up a video call path and a call processing server(140). The call processing server separates a voice signal from a video call traffic that is transmitted form the originating terminal. The voice signal is transmitted to a terminated MSC through a voice call path.
